Embarking on a DIY Endeavor: Know the ‘Golden Rule’ of Electrical

DIY electrical troubleshooting can be dangerous. However if you live by this ‘golden rule’ of electrical work, you’ll stay safe: You cannot suffer a shock if no electricity is present. Before beginning any electrical sleuthing or repair, always:

  1. Turn off the breaker on the appliance/outlet in question before beginning your project.
    Flip the breaker of the appliance/outlet in question to the OFF position. Touch the panel with one hand only, leaving the other at your side to reduce electrocution risk. Turning the breaker to the OFF position instantly removes electricity from the equation (provided you choose the correct breaker). When the power is OFF, electrical protection is ON.
  2. Place a piece of tape over the breaker, warning yourself/others.
    This will prevent the breaker from being accidentally turned ON while you are working.
  3. Check the outlet/wires/appliance with a non-contact electric tester.
    Even if you think the breaker is OFF, test with a non-contact pen-style electric tester. Available for less than $20, this is your best defense against mislabeled breakers/wires. These testers ring/flash if electricity is flowing, simply touch to the object in question.
  4. When working, recap wires.
    Like breakers, caps likewise lower the probability of mishap.
  5. Avoid working in moisture-prone areas.
    Be mindful of your work environment. Water and electricity don’t mix.

Outside the Comfort Zone: Electrical Issues that Require a Pro

These repair issues should always be attended to by a licensed electrician:

  • Dimming/Flickering Lights
    Lights that dim or flicker indicate a loose/faulty connection that require the expertise of an electrical pro for the fast detection and resolution necessary to prevent damage/fire.
  • Outlet Malfunctions
    Buzzing and burnt outlets, as well as loose outlets that cannot hold a plug, indicate a very old wiring system in need of attention. Is your home short on outlets, plagued with 2-prong/ungrounded outlets, or frequently tripping breakers? If so, it’s time for an update!
  • Repeated Breaker Trips
    If redistributing/reducing circuit load does not solve this issue, you likely have a short circuit resulting from dangerously exposed/touching wires, broken wires, a loose connection or a ground fault.
  • Humming/Buzzing from Breakers
    Humming/buzzing breakers indicate a faulty breaker that is overloaded and cannot trip. Flip it OFF manually, and get a pro out fast to prevent electrical fire.
  • Outdated Wiring
    Ancient knob-and-tube and unsafely installed aluminum wiring is extremely dangerous. If you skipped the home inspection at purchase and your house is older than your grandparents, you may need a whole home rewiring for safety.
  • Insufficient Power Supply
    Houses even a few decades old may require a bigger, better wiring system to power the glut of appliances and devices today’s families rely on. 60-amp service is no longer sufficient for modern homes.
  • Water Related Issues
    Any issues in moisture-prone areas, including problems involving plumbing, should be addressed by a pro.
